<br>
Is the file disk_out_ref.exo different from the file disk_out_ref.ex2<br>
that comes with the ParaView test data?<br>

>> There is a filter in VTK called vtkDistancePolyDataFilter. It takes two polydata as inputs and produces up two two outputs, each with an the (optionally) signed distance from each point in the first polydata to the closest point on the second polydata. If
the polydata inputs overlap and the signed distance is requested, the distance may be negative, which means that the point at which the distance is computed is inside the other polydata.<br>
